MUST BUY!!! (If you can find it)

Don't let the echo 1 name scare you into thinking this is just an overpriced rebrand of some lower quality manufacturer. The echo 1 master series Mp5 is worth every penny of the ~$300 price tag (depending on where you get it). The shame is that echo 1 only produced these for a short period of time so finding one can be pretty rare. I happened to pick mine up used from ebay for $175 which was a great deal. If I were to describe this rifle in one word it would be solid. both stock gearboxes work flawlessly even after 3 years of use, I've actually found the outdoor (red) gearbox is unnecessary as it shoots too hard and requires .28g and up bb's to keep them from curving up. The field gearbox shoots around 420 fps with .2g bbs which is a little hot for most fields while the indoor (Black) gearbox shoots a nice 350-360 fps which may be too hot for some cqb fields. ROF is average with about 12 on the red and 16 on the black. Range is where this beauty really stands out. The compression and internal parts on this rifle are outstanding I can out-range most dmr's with the indoor box included. with .28g bbs on the black gearbox I was shooting 297 fps with a 3 fps variance and I was hitting players accurately down the iron sights at distances of over 150ft. range increases slightly with the outdoor gearbox but fps isn't everything and I feel the indoor is more consistent and doesn't require .3g bbs to shoot accurately. also I would recommend buying a madbull 225mm 6.03 inner barrel. increasing the barrel length isn't necessary and it keeps the gun length short. The only issue I have is the rail is loose and the outer barrel with the charging handle has developed a slight gap. all issues that are expected to be normal of a 3 year old gun and can be fixed with some time and effort. all in all do yourself a favor and buy this gun if you get the chance YOU WILL NOT REGRET IT. Oh, and the whole quick change gearbox is nice I can change the whole character (dmr/cqb) of the gun in under a minute and you will amaze everyone standing next to you while you do it!
